'STOPPER FoR WIRE ROPE, aw.

SPECIFICATION forming part of Letters Patent No. 286,863, dated October16, 1883,

(No model.)

To all 10700172, it may concern Be it known that we, EBEN M. STODDARDand Jonn N. JOHNSON, citizens of the United States, at present residingat Norfolk, in the county of Norfolk and State of Virginia, haveinvented a certain new and useful Improvement in Stoppers for \VireRope, &c., of which the following is a specification, reference beinghad to the accompanying drawings, of which they are a part.

The object of our invention is to provide a stop which shall actautomatically to prevent a bar, rod, or rope from moving in but onedirection, but allow it to move freely in the other direction.

Figure 1 is a perspective view of our invention. Fig. 2 is a centralvertical section of the same. Figs. 8 and 4 are detail views of thevarious parts of the same.

Similar letters of reference refer to corresponding parts throughout thedifferent views.

A is the body of the stop, provided on its upper face with four wings, aa e c, all cast in one piece with the body, by preference of oval form.The wings a a are centrally slotted through their entire length, havingat their outer ends the shoulders M, forming abutments, for the purposeto be hereinafter de scribed. The wing e, at the side and midway betweenthe ends of the wings a a, is slotted throughout its entire length anddepth, the slot being continued through the body of the stop for thepurpose of allowing the insertion or removal of the rope or rod from thestop, said 1 wing c, at its inner end, being grooved to receive theT-head of akeeper, O, which is fitted to the slot in the wing, andfastened therein by a bolt, H, that passes transversely through both thewing and the keeper.

On the side of wings a a opposite wing e is a solid wing, e, whichserves the purpose of a strengthening-piece or brace.

The jaws B B are convexed on their adjacent faces and grooved, so as toconform to and embrace the rope or rod to be stopped; and

they are provided on their outer surfaces with knobs b b, for thepurpose of manipulating the jaws when it is desired to disengage themfrom the rope or rod. The outer ends of the jaws are tapered to fit intoand under the shoulders M M, for the purpose of holding them to theirwork.

The keeper 0 is inserted in the slot of wing e, and secured therein bythe T-head and set screw or bolt H.

The operation of our invention is as follows: To attach the stop to therope or rod, withdraw the set screw or bolt H, and this will allow thekeeper to be removed, after which pass the rope or rod through the slotin wing 0 into the opening between the jaws B B. Then replace and fastenthe keeper G. The jaws B B having free upward action, the rope or redcan be readily drawn upward; but when the rope or rod has a downwarddraft, the outerends of are dragged inwardly, and thus forced to bitethe rod or rope with a power proportioned to the downward draft uponsaid rod or rope.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The body A, provided with the slotted wings a a, in combination withthe jaws B B, having convened inner edges longitudinally grooved, as andfor the purpose herein set forth.

2. In combination with the body A, having the slotted wings a a and jawsB B, the T- headed keeper (3, as and for the purposeherein set forth.

3. The body A, wings a a e, jaws B B, shoulders M M, and keeper 0,combined as and for the purpose specified.
